Plasticizers are chemicals added to materials such as plastics and rubber to increase their flexibility and ductility. They can make materials softer and easier to process and use. There are many common plasticizers in life. Have you discovered them?

 

1. Phthalate plasticizers:
- Di (2-ethylhexyl) phthalate (DEHP): widely used in PVC (polyvinyl chloride) products, such as wires, cables, floors and toys.
- Di (2-ethylhexyl) phthalate (DINP): used in materials such as plastics, floors and hoses.

 

2. Fatty acid ester plasticizers:
- For example, plasticizers extracted from vegetable oils (such as soybean oil) or animal oils (such as lard) are often used in the processing of rubber and textiles.

 

3. Phosphate plasticizers:
- Commonly used to improve the fire resistance of plastics and rubber, and are also used in some high-performance plastics and cables.

 

4. Polyester plasticizers:
- Polyester plasticizers have low volatility and good high temperature resistance, and are usually used in plastic products that need to be durable for a long time.

 

These plasticizers are widely used in our daily lives, such as:
- Plastic packaging materials: such as soft plastic bags and food packaging.
- Floor materials: such as PVC flooring.
- Automotive parts: such as window seals, dashboards, etc.
- Toys: Especially children's toys, may contain plasticizers to increase flexibility.

 

However, it should be noted that some plasticizers, especially some phthalate plasticizers, may have potential health risks, especially for children and pregnant women. Therefore, many countries and regions have strictly restricted and managed the use of these plasticizers.
